Built-in Autoloader

Compatible with various types of plate adapters: 96-well standard (flat, U- and V-bottom) plates, 40-tube racks, and 40-EP tube racks, with flexible switching between single-tube measurement and batch mode.

One-click free switching between single tube and high-throughput modes without waiting

Compatible with various types of plate adapters:
96-well standard (U- and V-bottom, flat) plates,
1.5 ml 40-tube racks, 2 mL EP tube racks and
40-flow cytometry tube racks.

Magnetic suction hood

Ensure biosafety while avoiding light, and facil-
itate sample addition.

Patented mixing function

Single tube stirring and mixing

Mix each sample only once

Automatic cleaning at sample switching

Extremely low carry over pollution rate (0.05%)

Intelligent identification of test tube bottom and needle anti-collision system

Intelligent identification of sampling needle collision, and automatically alarming for it

Unattended maintenance process

One button shutdown, automatic cleaning, unattended operation.
Supporting automatic shutdown and power off after high-throughput measurement.

Light transmission

Independent fiber optic transmission corresponding to independent detection channels

Reducing the coupling between modules and improving the stability of the optical path;
After being subject to long distance transportation, laboratory moving, or environmental
vibration, excellent detection performance can be maintained for the optical path.
